Sometimes Periodic workManager gets called two times.

This is my built.gradle file:-

compileSdkVersion 28
minSdkVersion 22
targetSdkVersion 28
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

Here is this code:-

//---------------------------------------------------------Class Login---------------------------------------------------------------------------------------//
SaveData("Frist");

PeriodicWorkRequest periodicWorkRequest = new PeriodicWorkRequest.Builder(DailyLogoutTask.class,
1, TimeUnit.DAYS)
.build();
WorkManager.getInstance().enqueueUniquePeriodicWork("DailyTaskRestaurantLite"
, ExistingPeriodicWorkPolicy.KEEP
, periodicWorkRequest);

private void SaveData(String str) {
SharedPreferences.Editor preferencesEditor = mPreferences.edit();
preferencesEditor.putString("Status1", str);
preferencesEditor.apply();
}

//------------------------------------------------------Class DailyLogoutTask-----------------------------------------------------------------------//

If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue.
- A screenrecord or screenshots showing the issue (if UI related).
